NTS-5000LITE OCXO Time Server

NTS-5000 RUBIDIUM Time Server

Note! These site covers both product: the NTS-5000 (RUBIDIUM & OCXO) and NTS-5000LITE (OCXO only). The difference between these 2 products is RUBIDIUM quantum oscillator only. If you are interested just in NTS-5000LITE please disregard RUBIDIUM oscillator when reading below specification.

NTS-5000 and NTS-5000LITE delivers time directly to networks using NTP, PTP/IEEE1588 protocols. Standard (min.) configuration is equipped with x2 LAN 10/100Mbps. Number of LANs can be extended up to x10 1GE intefaces (SFP, RJ45). Each LAN extention card has private IP stack for (S)NTP/PTP. The PTP/IEEE1588 is PHY hardware timestamped and support all profiles. Cards are 100% isolated (no TCP/IP) using internal analogue synchornization signals. This ensures top cyber-security and let single NTS-5000 server support independent private networks. Each card can operate Master or Slave.

Server is equipped with x2 independent GNSS data inputs. They support independent NTS-antenna satellite receivers. Built-in holdover oscillator guarantees time for long period of missing GNSS signals. Both ANT1/ANT2 interfaces can be switched to output GNSS NMEA emulation mode - each with 1PPSout. Server can be synchronized to external clocks using 1PPS (PPM*,PPH*,5PPS*), IRIG-B, rs232, rs422/485. It also can provide additional reference output signals: PPS, IRIG-B, ToD, 10MHz, SYSPLEX and others.

NTS-5000 is STRATUM-1, PTP/IEEE1588 GRANDMASTER supporting hardware PHY stamps. It offers accuracy better than 200ns (NPL-UK test has measured typicaly better than 50ns - see ADEVTDEV). Server supports leap second and synchronizes UTC monotonously (jump-free). It can simultaneously serve up to 100,000 NTP clients. Firmware basis on FreeBSD UNIX - one of best stable operating systems ever. Server uptime is counted in years of 24/7.
